What is the period of a base ten expansion?

is it the number of repeating digits OR is it the number of non-repeating digits?|||It's the number of repeating digits in the decimal.


If the period starts at the first place after the


decimal point, we have a purely periodic expansion.


Examples:


0123123123... is purely periodic with period length 3.


0.0833333 is not purely periodic but does have a


period length of 1.
